To aZZ whom vit may concern.'

Be it known that l, ALEXANDER Hannan son', a citizen of' the United States of Ainsi-iw, residing at Detroit, in the county of sand or other impurities that are slightly embedded in the metal and unless these impurities are removed they will be worked into the inet-al, which would be very objectionable.

f The invention therefore has among the ob jects thereoiI to provide a machine which will etciently scalp the metal castings or the like; to provide a structure hy which opposite, faces of the bars, slabs or castings,

will be comp'. `Ately scalped as they pass through the machine; and to provide a niachine which may be easily and quickly adapted for various sizes of castings, etc.

Other objects of the invention will more tally-hereinafterappear. .l

Thevinvention resides in the novel constriliction,` arrangement and combination of parts as will be herein described and particularly pointed out in the claims.

ln the draWingsV-Figure l is a pla-n View ofamachineembodying the invention; Fig. 2 is an end elevation thereof; Fig. 3 is a section onthe `vline -fn oflig. 2; and Fig. ft is alside elevation. 5 'fria-designates the frame oi the machine, inounted uponsuitable legs B and having a plurality ospaced supports@ l) E and F extending longitudinally thereof. Ar-

rangedintermediate the supports C and D and jeiirnaled in bearings therein are a plurality of pairs of feed rollsl G H, l J and K L, the several pairs being spaced from each other. Positioned below the line of Ifeed and mounted in bearings in the meinbers G D fi Lsca'lping rolll/i, and above the line of feed; intermediate the pairs of feed rolls l 'J and K L a second scalpingroll N. A i, l

0 and P designate hacking rolls for the nienibes M N, respectively. Each of the scalping rolls is provided ad* jacent thereto with a work-positioning roll Q; lwhich forms a guide for regulating the amount. oit metal reinoned from the Work;

The shafts R and` Sof each pair o 'feed rolls project beyond the support l) and the projections of these shafts are rigidly connected as by suitable coupling members T with shafts U V. alined therewith and which are suitably journaled in bearings in the supports E F.

iV and Xare interineshing pinions fixed' respectively to the shafts V, and Y is the main driving' pulley, the shaft of which isy journaled in the support F and has thereonr a main driving pinion Z. L A is a gear Wheel fixed to the shaft U oit the roll I and meshing with the gear Z. B C are gear wheels-fixed respectively to the shafts V of the rolls 'H and L and en!` gaining the gear wheel A. k rihe gear Wheels A B C are of the sanie size and also the pinions N and X are of; complementary size, thereby eil'eeting a driv'l'. ing of the several pairs of feed rolls at the same speed. Thenieinhers '0 P and @are preferably idlers. y ,fk The shafts of the scalping rollsl have" extensions D? journaled at their outer ends` in the support E, and fixed 'to these enten,

sions intermediate the-supports D and EA are driving pulleys E which are connected," hysuitable belting not shown, to any `desirable source of power. noticed that Athe seal-ping rolls are driven?r` independently oi the drive trains for the@ feed rolls. I f if @ne meinber off each pair of the feed rolls,Tv as G, l vand L, is suitably mounted in ver-, tical adjustable bearings F', eachv bearing; being yieldshly pressed toward the cooperating roll by a spring' G', thev tension Aoil which may he regulated by a screw H provided with a hand-Wheel l. The inward;

limits oi Jhe bearings F of the rolls G and4 bearings F of the roll'l may he sinnla regulated. The bearins M of rolls O and l), and t e bearthe guide rolls Q, are vertically Thus it will lf desired, the inward 1nove-N 'though not spring-pressed` As shown, the bearings M have connected thereto as by a swivel joint, a rod O which has screw-threaded engagement with a bearing P in the support and projects above the latter, the projection having fixed thereupon a worm gear Q.

Extending laterally of the supports d and D and journaled in bearings It thereon, is a shaft S having worms T at opposite ends thereofintermeshing with the worm gears of the cooperating bearings M of the backing rolls. This shaft is provided with a handwheel U and by rotating the handwheel the shaft S will be revolved, and through the medium ofthe worms and worm gears, effect :x simultaneous and corresponding adjustment, of the cooperating bearings for the backing roll.

The bearing N for the guide roll Q is provided with a suitable screw V and handwheel-IV by which the guide roll maybe adjusted. By lowering or raising the guide roll the amount. of metal removed from the casting or other work passing through the machine, may be regulated.

The scalping 'rolls areprovided with removable knives or blades X preferably arranged at an angle to the axis of the roll, and positioned beyond the scalping roll N is a rotary brush Y for removing from the top surface of the casting or work, any loose meta that remains after the scalping thereof. Preferably this brush is at an.

The member Y suitable manner, but

angle to the scalping roll. may be driven in any I find it desirable to drive the samefrom the scalping roll N as by means of the pulleys A2 B2 and belt C2. In order to insure a very thorough removal of all the cuttings and shavings from the casting or work, a blower pipe DZ is positioned slightly in advance of the rotary brush Y, the blower receiving its supply of compressed air from any suitable source.,

In operation, powerbeing'supplied to the main driving pulley and the pulleys of the scalping rolls, the latter and the feed rolls are rotated in thedirection of the arrows on Fig. 3. The casting, bar, slab or the like is then fed to the rolls G H, which move it forward intermediate theroll -M and its backing roll O. As the casting passes across the roll M the lower face is completely scalped, since as shown in Fig. l, the knives X extend from end to end of the scalping roll. The casting passes ffrom the scalping roll M to the feed rolls I'fand J, which are spaced from the rolls G I-I a distance less than the length of the castings, bars or the like that are to be scalped, so that the second pair of feed rolls will engage the casting before the lat-ter leaves tne rst pair offeed rolls. The members I .I continue to feed the work forward across the member 'M and to `the rollsN and P, where the upper face of the casting is completely scalped. The cuttings, shavings, etc., which remain upon the upper face of the casting will he removed by the rotary brush as the metal passes to the rolls II L, the finer 'shavings, dust, etc., being blown from the upper surface by the compressed air discharging from the pipe D2. hus, as will be apparent, the passage of the work through the machine is continuous and in substantially a straight line, while opposite faces of thecasting or other work are properly and con'ipletely scalped in one operation.

As hereinbefore stated, by raising or lowering the guide roll Q the amount of j metal-ren'ioved by the scalping roll may be regulated. Also by regulating the various feed and backing rolls the machine may be readily adapted for any slab or casting within certain limits.

Although I have shown and described the preferred form of my invention, I do not desire to limit my protection to the structure illustrated, buttonsider the invention broad enough to cover various and obvious changes which might be made and which would fall within the scope of these claims.

lNhat I claim as my'invention is l. In a metal scalping machine, the combination with scalping rolls upon opposite sides of the line of feed, rolls operatively positioned in relation to said scalping rolls and means for limiting the adjustment of said rolls.
